Its hardcoded. :'(

Isnt there something that allows twin SBs in a grav well?  Ive run past it possibly DS that gives the grav well an extra sb.

There is both a research modifier and a planet bonus modifier that allow you to increase the max number of SBs....the max number of SBs (before planet bonus and research modifiers) could also have been increased for the planets in that mod...that's how stars allow 4 SBs....

In this case, my mod grants the research modifier. The issue is however when you build a Vasari rebel SB and try to move it to another gravity well, regardless if it has a SB (or ever had one for that matter), the game believes there is already a starbase and rejects the order.

By itself; I construct a single starbase and try to move it to an adjacent world that has no starbases. The game denies the move claiming I already have a starbase in that gravity well.

I'm sort of wondering what logic they are using in the hard code. If I was implementing this, I would use something along the lines of "if target_grav_sbcount >= player_max_sb_count then deny" or "if target_grav_sbcount > 1 then deny".

Right now, it seems more of a "if target_grav_maxsbcount > 1 then deny" logic.

I'd say that is probably it. It's annoying too since they don't seem interested in changing it
